APT29 is a Russia-linked nation-state threat actor known as Cozy Bear, CozyDuke, The Dukes, Midnight Blizzard, Nobelium, BlueBravo, and Cloaked Ursa. Its SolarWinds-related activity has also been tracked under names including UNC2452, Dark Halo, and SolarStorm. Its operations include software supply-chain compromise, exploitation of internet-facing enterprise services, targeted phishing, credential theft, and theft of email data. APT29 gained access to victims through trojanized SolarWinds Orion updates. It has also exploited vulnerabilities in Citrix, Pulse Secure, FortiGate, Zimbra, Microsoft Exchange, and JetBrains TeamCity, including CVE-2023-42793. Other initial-access methods include spearphishing links and attachments, password spraying, and the use of compromised identities to authenticate to SSH, VPNs, and other remote-access services. Following compromise, APT29 enumerates remote systems using AdFind, obtains credentials using tools such as Mimikatz, and requests Kerberos service tickets for offline password cracking. It has attempted to retrieve Group Managed Service Account passwords. Lateral movement includes RDP connections from public-facing systems to internal servers, remote scheduled tasks, and the use of different compromised accounts for remote access and internal movement. It compresses stolen email into password-protected archives before exfiltration. APT29 uses command shells, encoded PowerShell, Cobalt Strike, and malware such as Raindrop. Its command-and-control methods include TCP communications and Tor-based forwarding for remote access. Defense-evasion practices include payload encoding and decoding, command-and-control infrastructure that resembles legitimate victim infrastructure, and VPN infrastructure located in victims' countries.

Named as the possible attribution for the Russia-linked espionage operator behind the AI-assisted implant rebuilding activity. The reference does not conclusively establish that GTG-20006 and Midnight Blizzard are the same actor.
Russian intelligence-linked actor cited for attempts to steal COVID-19 vaccine development and testing information, illustrating healthcare-related espionage.
Mentioned as the attributed operator of early ConsentFix v3 campaigns. The toolkit socially engineers victims into handing over legitimate OAuth authorization codes, which attackers redeem for tokens to access Microsoft 365 services.
Linked to CaptiveCrunch, a campaign manipulating guest-network captive portals to deliver malware and steal credentials and cloud session tokens from travelers. Its operational sub-cluster Storm-2945 conducts the activity, which can lead from device infection to corporate account compromise.
